The United Food and Commercial Workers wants to call public attention to the crying scandal of a Wal-Mart grocery in Henderson, Nevada's starting workers at $6.75 an hour. So what does it do? It hires temp workers at $6/hour with no benefits to walk a picket line in 104-degree heat in front of the air-conditioned store. Picketer Sal Rivera, as it happens, used to work at Wal-Mart, where he made $8.63 an hour, a good deal above what the union paid him to picket; he'd consider re-applying.
